The Development of Integrated CAD/CAM System on Engineering Workstation 870927

ABSTRACT

This paper describes an integrated CAD/CAM system on an EWS. This system is based on the CAD and CAM systems on large scale computers which have been developed and put into practical use in Toyota Motor Corporation. All the functions of these systems are compactly integrated into this system. We have established the following technologies through its development.

A method for construction of data structure common to CAD and CAM

A database structure that enables efficient data retrievals

Owing to these technologies, a non-expensive integrated CAD/CAM system on an EWS has been developed, which can be introduced in small-sized parts suppliers. This system has already been put into practical use since early 1988, and used by more than ten suppliers. Much more suppliers are also planning to introduce this system in near future.
